This turned out to be a crummy idea.  For the technical reasons behind that
see my recent post to the plplot-devel list.  However, that same post
details how I tried the only other alternative (mixing C++ and C object code
in the same library), and that apparently works on Linux (and maybe all
other systems as well?).

The current status is the CVS version of PLplot should give a static build
of PLplot libraries (including the C++ wxwidgets and psttf devices) that
passes all build-tree tests, but there is still a minor problem (library
ordering issue) for the install tree tests which I will deal with tomorrow.

Note, this PLplot "static build" is still not what Joe wants since even
though the PLplot libraries are all statically linked together for this
case, the external linking is still shared.  I think the solution to making
even the external linking shared is simply to impose the -Bstatic link
option on top of the static PLplot build (once that completely works), but I
haven't tried that yet, and I am sure there will be minor but time-consuming
issues to sort out.

Joe, you have come up with an interesting problem that now has me hooked, but
it will probably be next week before I can come up with the definitive answer.
